| 摘 要： | 芍药进入设施栽培后，常发生一种枝叶枯萎现象，危害严重。为明确病害发生原因，了解发病规律，笔者对北京地区设施栽培的芍药枝叶枯萎现象进行定期观察。通过分离培养、病原菌形态特征和寄主范围测定，鉴定该病为芍药灰霉病，其病原菌为半知菌亚门葡萄孢属灰葡萄孢Botrytis cinerea Pers.。研究表明，该菌生长产孢的温度范围是4~28℃，最适合的温度范围是16~24℃；pH 2~11范围都可以生长，最适的pH范围是3~5，pH为2时不能产孢；光照对菌落生长和产孢影响显著，给予一定光照有利于菌丝生长，黑暗有利于产孢，连续光照下不能产生孢子。

| Abstract: | When moved under protected cultivation,the herbaceous peony often suffers from a leaf and branch wilt,causing serious damage. In order to clarify the causes and understand the occurrence regularity of the disease,the author regularly observed the occurrence of the disease. According to its symptom,pathogenic fungi isolation,pathogenic fungi morphologic characters and host range,it was identified that the wilt was caused by gray mould. The pathogen wasBotrytis cinerea Pers. Research showed that the temperatu... |
